Description

传输灵活以太网的数据流的方法、发射机和接收机 技术领域
本发明实施例涉及以太网领域，并且更为具体地，涉及一种传输灵活以太网的数据流的方法、发射机和接收机。
背景技术
灵活以太网(FlexEth)概念的引入，为以太网物理连接的虚拟化，提供了一个可行的演进方向。具体而言，在FlexEth中，可以按照一定的顺序将一个或多个物理连接级联在一起，构成一个物理连接组，该物理连接组相当于收发两端的一个逻辑连接，该逻辑连接的接口带宽可以看做该物理连接组内的各物理连接的带宽之和。因此，FlexEth根据实际需要，通过级联不同的物理连接，可以配置出不同带宽的逻辑连接，与传统的依赖于物理连接的以太网相比，更加灵活。
在FlexEth中，发送端会将逻辑连接上的数据流分配到物理连接组内的各物理连接上进行并行传输，而发送端对数据流的分配正是按照物理连接在物理连接组内的顺序进行的，也就是说，在一定周期内，顺序越靠前的物理连接上分配的子流在整个数据流中的位置也越靠前。接收端接收到物理连接组内各个物理连接传输的子流后，需要按照与发送端相同的顺序组装各子流，进而恢复出该逻辑连接上的数据流。因此，组内的各物理连接在并行传输子流的过程中，不但要向接收端指示各自的标识，还要为接收端标识出物理连 接组内的各物理连接之间的先后顺序关系，以便于接收端恢复数据流。
现有技术为了实现物理连接组内各物理连接的先后顺序的标识，在每个子流的开销区域(开销码块所包含的比特区域)中传输多张物理连接组配置交互地图，这种方式会传输很多冗余的信息，浪费开销区域的资源，而且传输多张物理连接组配置交互地图耗时较长，导致传输效率低下。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
为了便于理解，先对现有技术进行简单描述。
图1示出了灵活以太网的数据帧结构。在图1中，在一个子帧周期内，FlexEth开销码块(Overhead)后跟随若干个64×66b结构的信息码块，例如20480个64×66b结构的信息码块。连续的若干个子帧周期(通常为4个子帧)构成一个基本帧(BasicFrame)。连续的若干个基本帧(通常为40个基本帧)构成一个超帧(SupperFrame)。
现有技术对物理连接组内成员的顺序的标识正是在开销码块组成的开销区域中进行的。具体而言，发送端通过物理连接组向接收端传输数据流的过程中，发送端会按照物理连接组内的各物理连接的先后顺序将数据流分配到各物理连接上，物理连接在物理连接组内的顺序越靠前，其负责传输的子流在整个数据流中的位置也靠前。当数据流分配完毕之后，每个物理连接就会传输各自分配到的子流。灵活以太网的在物理接口上传输的每个子流是以数据帧的形式传输的，每个物理连接上传输的数据帧具有图2所示的周期性结构，其中，1个基本帧通常由4个子帧组成，每个子帧的头部设置有一个开销码块，共4个开销码块。FlexEth的一个信息码块通常包括66比特，这4个开销码块的4×66比特共同构成了图2所示的开销区域210，现有技术正是利用 该开销区域对物理连接组的配置进行指示的。表1示出了现有技术中的开销区域210的一部分(31比特之前)。
表1现有技术中的开销区域210的一部分
Figure PCTCN2016087312-appb-000001
其中，This PHY为本物理连接的标识，FlexE Group Number为This PHY所属物理连接组的标识。现有技术对物理连接组内各物理连接之间的顺序正是通过PHY MAP进行标识的，下面进行详细论述。
如表1所示，This PHY占8比特，意味着现有技术中的一个物理连接组最多可以有256个物理连接，现有技术在PHY MAP字段以地图的方式(每个物理连接通过地图中的1个比特进行指示)指示256个成员哪些属于该物理连接组，哪些不属于该物理连接组。由于PHY MAP在一个基本帧周期仅占13个比特，为了指示256个物理连接是否属于该物理连接组，至少需要20个基本帧周期才能形成一张完整的地图。但现有技术并不止于此，它还通过PHY Map字段指示物理连接组配置的更新(即物理连接组内的物理连接的个数和/或先后顺序发生变化)过程，具体参见表2。
表2 PHY MAP的信息格式
Figure PCTCN2016087312-appb-000002
从表2可以看出，40个周期的PHY MAP字段会承载2张地图，其中一张地图由20个基本帧周期的PHY MAP Request字段组成，另一张地图由20个基本帧周期的PHY MAP Active字段组成，分别用于请求更新物理连接组的配置和激活物理连接组的新配置。2张地图的传输共需40个基本帧周期。需要说明的是，通过PHY MAP字段传输的地图，接收端仅能获知256个成员哪些属于本物理连接组，哪些不属于本物理连接组，为了实现物理连接组内各物理连接之间顺序的指示，现有技术还约定256个成员中，This PHY标识越大的物理连接，在本物理连接组内的顺序越靠后。在上述约定的前体现，现有技术通过传输多张地图实现了物理连接组内各物理连接之间顺序的标识。
下面结合图3，详细描述本发明实施例的传输灵活以太网的数据流的方法。
图3是本发明实施例的传输灵活以太网的数据流的方法的示意性流程图。图3的方法可以由发送端执行，该方法包括：
310、获取待传输的数据流，其中，数据流准备通过发送端与接收端之间的物理连接组传输，物理连接组包括N个物理连接。
应理解，在灵活以太网中，通过物理连接组传输的数据流可以看成通过发送端与接收端之间的逻辑连接传输的数据流，该逻辑连接的接口带宽可以是物理连接组内各物理连接的接口带宽之和。此外，在灵活以太网中，可以根据实际需要，灵活调整传输数据流的物理连接组的配置，即灵活调整物理连接组的物理连接的个数以及各物理连接的先后顺序。
此外，通过物理连接组传输数据流可以理解为通过多个以太网物理接口传输数据流。
320、根据N个物理连接在物理连接组内的先后顺序，将数据流分配至N个物理连接上，得到N个物理连接分别对应的N个子流。
应理解，分配到N个物理连接上的N个子流(或称子数据流)可具有如图1所示的特定的数据帧结构。
应理解，N个物理连接和N个子流具有一一对应关系，即一个物理连接负责传输N个子流中的一个子流。还应理解，步骤320具体可包括：将数据流分割成N个子流；按照N个物理连接在物理连接组内的先后顺序，确定N个物理连接各自负责传输的子流，其中，物理连接组内排序靠前的物理连接负责传输的子流在数据流中的位置也靠前。
330、通过N个物理连接传输N个子流，其中，每个物理连接上传输的子流包括每个物理连接的配置状态信息，配置状态信息包括每个物理连接的标识，以及物理连接组内与每个物理连接相邻的物理连接的标识，N个物理连接的配置状态信息共同指示N个物理连接的先后顺序。
具体而言，一个物理连接上仅传输该物理连接的标识，以及物理连接组内与该物理连接相邻的物理连接的标识。虽然接收端收到一个物理连接上的配置状态信息之后仅得到该物理连接相关的局部相邻关系，但接收端将组内所有物理连接的配置状态信息汇总之后，就可以恢复出物理连接组内各物理连接之间的先后顺序。
应理解，上述N个物理连接传输N个子流可以是N个物理连接并行地传输N个子流。
还应理解，当物理连接为物理连接组中排在首位的物理连接时，与该物理连接相邻的上一物理连接可以为空，或者，可以为该物理连接组内排在末 位的物理连接；同理，当物理连接为物理连接组中排在末位的物理连接时，与该物理连接相邻的下一物理连接可以为空，或者，可以为该物理连接组内排在首位的物理连接。
本发明实施例通过在每个物理连接的子流中携带该物理连接以及与该物理连接相邻的物理连接的标识，接收端利用物理连接组中各物理连接的局部相邻关系，能够恢复出物理连接组内各物理连接之间的先后顺序关系，与传统的传输多张地图的方式相比，节省了标识物理连接组内各物理连接先后顺序的开销，提高了传输效率。
可选地，作为一个实施例，物理连接组内的每个物理连接上传输的子流还包括该物理连接组的标识。
例如，发送端与接收端之间可以设置多个物理连接组，每个物理连接上可以同时传输物理连接组的标识和物理连接的标识，这样接收端就可以识别出是哪个物理连接组上的哪个物理连接在传输数据流。
可选地，作为一个实施例，每个物理连接的配置状态信息包含在每个物理连接上传输的子流的开销码块中。
具体地，每个物理连接的配置状态信息可以设置在一个基本帧周期内的开销码块中，例如，一个基本帧周期可以包括4个开销码块，以上配置状态信息可以设置在第1个开销码块中，也可以设置在4个开销码块组成的开销区域的任意位置，本发明实施例对此不作具体限定。
可选地，作为一个实施例，每个物理连接的配置状态信息以基本帧为单位周期性传输。
本发明实施例中，物理连接组内的每个物理连接以基本帧为单位周期性 传输其配置状态信息，这样，物理连接组内所有成员会在一个基本帧周期内将各自的配置状态信息发送至接收端，接收端就可以利用各个成员的配置状态信息恢复数据流，而在现有技术中，以上过程需要40个基本帧周期才能完成。因此，本发明实施例与现有技术相比，提高了物理连接组配置的传输效率。此外，在现有技术中，为了保证收发端物理连接组配置的一致性，通常要求物理连接组的配置在一个超帧周期内保持不变，如果按照现有技术的方式传输物理连接组的配置信息，超帧周期至少需要设置为40个基本帧周期，而按照本发明实施例的方式，由于1个基本帧周期即可完成物理连接组的配置信息的传输，超帧的周期可以设置为1个基本帧周期，而超帧周期的缩短意味着允许系统配置在更短的时间变化，提高了系统配置的灵活性。
可选地，作为一个实施例，物理连接组内的与每个物理连接相邻的物理连接可包括：每个物理连接在物理连接组内的上一物理连接，和/或每个物理连接在物理连接组内的下一物理连接。
具体地，下面结合表3，以物理连接组内的与每个物理连接相邻的物理连接为该每个物理连接在物理连接组内的下一物理连接为例进行举例说明。
表3本发明实施例的开销区域210的一部分
Figure PCTCN2016087312-appb-000003
在表3中，基本帧中的第一开销码块的8至15比特指示物理连接组的标识，16至23比特指示本物理连接的标识，24至31比特指示该本物理连接的下一物理连接的标识。需要说明的是，上述标识所占的比特数，以及标识在开 销区域中的位置仅仅是举例说明，实际中，可以综合考虑开销区域的大小，标识的大小，以及开销区域所需携带的其他指示信息等因素为上述标识分配合适的比特数和比特位置。
具体而言，假设上述物理连接组的标识为A，该物理连接组A中包括3个物理连接，标识分别为2、7和4，其中，物理连接组A中的物理连接的先后顺序依次为：物理连接2，物理连接7和物理连接4。该3个物理连接均可按照表3所示的方式传输配置状态信息，即物理连接2在开销区域传输：物理连接组的标识为A、本物理连接标识为2、下一物理连接标识为7；物理连接7在开销区域传输：物理连接组的标识为A、本物理连接标识为7、下一物理连接标识为4；物理连接4在开销区域传输：物理连接组的标识为A、本物理连接标识为4、下一物理连接标识为空(即Null，表示当前物理连接4为物理连接组A中排在末位的物理连接)。接收端收到上述3种配置状态信息之后，按照图4中的箭头所示的链接方式组合得到物理连接之间的先后顺序，即物理连接2→物理连接7→物理连接4，相当于利用单向链表的方式标识了物理连接组内各物理连接的先后顺序。
需要说明的是，物理连接的标识为空的指示方式可以有多种，以This PHY的长度为8比特为例，可以将0x00和/或0xFF定义为空，当然，也可以使用其他专有定义。
可选地，作为一个实施例，物理连接组内与每个物理连接相邻的物理连接可包括：每个物理连接在该物理连接组内的上一物理连接。本发明实施例中，每个物理连接对应的开销区域可以与表3所示的开销区域类似，仅需将表3中的下一物理连接的标识替换成上一物理连接的标识。
具体而言，假设物理连接组的标识为A，该物理连接组A中包括3个物理连接，标识分别为2、7和4，其中，物理连接组A中的物理连接的先后顺序依次为：物理连接2，物理连接7和物理连接4。该3个物理连接均可按照本实施例描述的方式传输配置状态信息，即物理连接2在开销区域传输：物理连接组的标识为A、本物理连接标识为2、上一物理连接标识为空(即Null，表示本物理连接2为物理连接组A中排在首位的物理连接)；物理连接7在开销区域传输：物理连接组的标识为A、本物理连接标识为7、上一物理连接标识为2；物理连接4在开销区域传输：物理连接组的标识为A、本物理连接标识为4、上一物理连接标识为7。接收端收到上述3种配置状态信息之后，按照图5中的箭头所示的链接方式组合得到物理连接之间的顺序关系，即物理连接2→物理连接7→物理连接4，相当于利用单向链表的方式标识了物理连接组内各物理连接的先后顺序。
可选地，作为一个实施例，物理连接组内与每个物理连接相邻的物理连接可包括：每个物理连接在该物理连接组内的上一物理连接和每个物理连接在该物理连接组内的下一物理连接。
本发明实施例中，每个物理连接对应的开销区域可以与表3类似，仅需在表3所示的开销区域中的未被使用的字段中再定义一个字段，用于承载本物理连接的上一物理连接的标识即可。具体而言，假设物理连接组的标识为A，该物理连接组A中包括3个物理连接，标识分别为2、7和4，其中，物理连接组A中的物理连接的先后顺序依次为：物理连接2，物理连接7和物理连接4。该3个物理连接均可按照本实施例描述的方式传输配置状态信息，即物理连接2在开销区域传输：物理连接组的标识为A、上一物理连接的标识为空 (即Null，表示本物理连接为物理连接组A中排在首位的物理连接)，本物理连接标识为2、下一物理连接标识为7；物理连接7在开销区域传输：物理连接组的标识为A、上一物理连接的标识为2，本物理连接标识为7、下一物理连接标识为4；物理连接4在开销区域传输：物理连接组的标识为A、上一物理连接的标识为7，本物理连接标识为4、下一物理连接标识为空(即Null，表示本物理连接为物理连接组A中排在末位的物理连接)。接收端收到上述3种配置状态信息之后，按照图6中的箭头所示的链接方式组合得到物理连接之间的顺序关系，即物理连接2→物理连接7→物理连接4，相当于使用双向链表的方式标识物理连接组中各物理连接之间的先后顺序。
可选地，作为一个实施例，每个物理连接的配置状态信息还包括：第一指示信息和/或第二指示信息，第一指示信息用于指示每个物理连接是否为物理连接组内排在首位的物理连接，第二指示信息用于指示每个物理连接是否为物理连接组内的排在末尾的物理连接。
本发明实施例中，每个物理连接对应的开销区域与表3类似，仅需在表3所示的开销区域中再定义3个字段，分别用于承载本物理连接的上一物理连接的标识，第一指示信息，以及第二指示信息。
具体而言，假设物理连接组的标识为A，该物理连接组A中包括3个物理连接，标识分别为2、7和4，其中，物理连接组A中的物理连接的先后顺序依次为：物理连接2，物理连接7和物理连接4。该3个物理连接均可按照本实施例描述的方式传输配置状态信息，即物理连接2在开销区域传输：物理连接组的标识为A、上一物理连接的标识为空，本物理连接标识为2、下一物理连接标识为7，第一指示信息指示本物理连接为物理连接组内排在首位的物理 连接，第二指示信息指示本物理连接不是物理连接组内排在末位的物理连接；物理连接7在开销区域传输：物理连接组A、上一物理连接的标识为2，本物理连接标识7、下一物理连接标识4，第一指示信息指示本物理连接不是物理连接组内排在首位的物理连接，第二指示信息指示本物理连接不是物理连接组内排在末位的物理连接；物理连接4在开销区域传输：物理连接组A、上一物理连接的标识为7，本物理连接标识4、下一物理连接标识为空，第一指示信息指示本物理连接不是物理连接组内排在首位的物理连接，第二指示信息指示本物理连接是物理连接组内排在末位的物理连接。接收端收到上述3种配置状态信息之后，按照图7中的箭头所示的链接方式组合得到物理连接之间的顺序关系，即物理连接2→物理连接7→物理连接4，相当于利用双向链表的方式标识了物理连接组中各物理连接的先后顺序。
可选地，作为一个实施例，物理连接组内的每个物理连接的配置状态信息包括：该每个物理连接的标识；该每个物理连接在物理连接组内的上一物理连接的标识；该每个物理连接在物理连接组内的下一物理连接的标识；指示该每个物理连接的上一物理连接是否为物理连接组内排在首位的物理连接的信息；指示该每个物理连接的下一物理连接是否为物理连接组内排在末尾的物理连接的信息，具体参见图8。本实施例也是通过双向链表的方式标识物理连接组中各物理连接的先后顺序。
可选地，作为一个实施例，可以将物理连接组内排在首位的物理连接的上一物理连接设置为该物理连接组内排在末尾的物理连接；将物理连接组内排在末尾的物理连接的下一物理连接设置为物理连接组内排在首位的物理连接，即以双向环形链表的方式标识物理连接组中各物理连接的先后顺序， 具体参见图9。
可选地，作为一个实施例，每个物理连接上传输的子流还包括第三指示信息，图3的方法还可包括：当物理连接组内的物理连接的个数和/或物理连接组内的物理连接的先后顺序发生变化时，通过第三指示信息与接收端协商，对物理连接组进行更新。
为了便于描述，将物理连接组内的物理连接的个数和/或物理连接组内的物理连接的先后顺序发生变化称为物理连接组的配置的更新，上述第三指示信息可以在物理连接组的配置发生更新时，用于收发双方交互协商。举例说明，第三指示信息包括2个比特为，一个用于发送端请求物理连接组配置的更新，一个用于接收端确认物理连接组配置的更新。此外，上述第三指示信息可以承载于每个物理连接上的开销码块中，即属于开销区域的一部分。
本发明实施例中，通过第三指示信息指示发送端与接收端之间的物理连接组的配置的更新，与现有技术中的通过PHY MAP Request和PHY MAP ACTIVE的方式交互物理连接组配置的更新方式相比，节省了开销区域的资源，提高了物理连接组配置更新的效率。
应理解，接收端与发送端可以先通过上述第三指示信息对物理连接组的配置的更新进行协商，并约定当前帧周期内的数据流的收发还是基于更新前的物理连接组的配置进行。新配置在当前帧周期发送到收端，收端收妥物理连接组的配置信息，获得更新后全局配置，并在收妥更新的配置信息的当前帧周期的下一个或n个帧周期(具体时间可以由收发端协商)，收发端按照经过协商确认的更新后的物理连接组的配置进行数据流的收发。依次类推，形成配置更新与数据更新的流水线。具体参见表4。
表4物理连接组配置的更新和数据收发所基于的物理连接组的配置的关系表
Figure PCTCN2016087312-appb-000004
从表4可以看出，即使物理连接组的配置在一个超帧周期内进行了更新，本基本帧周期的数据收发仍然是基于更新前的物理连接组的配置进行，直到下一基本帧周期到来。
需要说明的是，上述第三指示信息的具体形式和使用方式可以视情况而定。可选地，作为一种实现方式，第三指示信息可以仅包含1个比特，如表5所示的确认比特ack，该确认比特ack用于接收端确认物理连接组配置的更新。下面结合图10详细描述基于1个确认比特的物理连接组的配置更新过程。
表5本发明实施例的开销区域210的一部分
Figure PCTCN2016087312-appb-000005
假设物理连接组在配置更新前包括4个物理连接，按先后顺序依次为物 理连接A7、物理连接A2、物理连接A9和物理连接A6。配置更新后的物理连接组添加了一个物理连接A3。物理连接组的配置更新过程可以采用图10所示的方式进行。需要说明的是，图10中的物理连接标识A7可以表示Group ID＝A，This PHY＝7的物理连接，当然，Group ID的携带是可选的，可以在每个物理连接的子流中携带Group ID，也可以仅在第一个物理连接或某些物理连接携带Group ID，当物理连接组之间的物理连接的This PHY不重合时，甚至可以不携带Group ID。图10描述的物理连接组的配置更新过程的具体步骤如下：
步骤0、物理连接组配置更新前，该物理连接组内的物理连接按照更新前的配置传输数据流。
步骤1、物理连接组通过添加新的物理连接A3，对物理连接组的配置进行了更新。
步骤1中可以先不指示A3与物理连接组内的其他物理连接之间的连接关系。物理连接组添加了新的A3物理连接，相当于以隐式方式向接收端发送了物理连接组配置的更新请求。
步骤2、接收端确认物理连接组配置的更新，将开销区域中的确认比特A置为1。
步骤3、发送端按照更新后的物理连接组的配置传输数据流。
此时，发送端需要更改物理连接组内成员的连接关系(如图10中步骤3的箭头所示)，完成物理连接组的配置的更新。
可选地，作为另一种实现方式，可以在开销区域中设置如下表6所示的请求比特R(Request)和确认比特A(Ack)，其中，请求比特R用于发送端 发送物理连接组的配置更新请求，确认比特A用于接收端对物理连接组的配置更新进行确认。
表6本发明实施例的开销区域210的一部分
Figure PCTCN2016087312-appb-000006
假设更新前的物理连接组包括4个物理连接，按先后顺序依次为物理连接A7、物理连接A2、物理连接A9和物理连接A6。更新后的物理连接组添加了一个物理连接A3。下面结合图11详细描述基于请求比特和确认比特的物理连接组的配置更新过程。具体步骤如下：
步骤0、物理连接组配置更新前，该物理连接组内的物理连接按照更新前的配置传输数据流。
步骤1、物理连接组通过添加新的物理连接A3，对物理连接组的配置进行了更新。
该步骤为可选步骤，可以不执行步骤1，直接执行步骤2。
步骤2、发送端将开销区域中的请求比特R设置为1，向接收端发送物理连接组配置更新请求。
步骤3、接收端将开销区域中的确认比特A设置为1，对物理连接组的配置更新进行确认。
步骤4、发送端按照更新后的物理连接组的配置传输数据流。
此时，发送端需要更改物理连接组内成员的连接关系(如图11中步骤4的箭头所示)，完成物理连接组的配置的更新。
上文中结合图1至图11，从发送端的角度详细描述了根据本发明实施例的传输灵活以太网的数据流的方法，下面将结合图12，从接收端的角度描述根据本发明实施例的传输灵活以太网的数据流的方法。
应理解，发送端侧描述的发送端与接收端的交互及相关特性、功能等与接收端侧的描述相应，为了简洁，适当省略重复的描述。

1220、根据N个物理连接的先后顺序，组装N个子流，以恢复数据流。
应理解，在步骤1220中，接收端恢复数据流所基于的N个物理连接的先后顺序不一定是从1210中的N个物理连接的配置状态信息中获得的。例如，可以从1210中获得该物理连接组内各物理连接的先后顺序，也可以使用之前已经获得的物理连接组内各物理连接的先后顺序。
本发明实施例通过在每个物理连接的子流中携带该物理连接以及与该物理连接相邻的物理连接的标识，接收端利用物理连接组中各物理连接的局部相邻关系，能够恢复出物理连接组内各物理连接之间的先后顺序关系，与传统的传输多张地图的方式相比，节省了标识物理连接组内各物理连接先后顺序的开销，提高了传输效率。

下面结合图17，给出本发明另一实施例。
图17是本发明另一实施例的传输灵活以太网的数据流的方法的示意性流程图。图17的方法可以由发送端执行，该方法包括：
1710、获取待传输的数据流，其中，所述数据流准备通过发送端与接收端之间的物理连接组传输，所述物理连接组包括N个物理连接；
1720、根据所述N个物理连接在所述物理连接组内的先后顺序，将所述数据流分配至所述N个物理连接上，得到所述N个物理连接分别对应的N个子流；
1730、通过所述N个物理连接传输所述N个子流，其中，每个物理连接上传输的子流包括所述每个物理连接的配置状态信息，所述配置状态信息包括所述每个物理连接的标识，以及所述物理连接组内的地图信息，所述地图信息包括M个比特，M为所述物理连接组所能容纳的总物理连接数，其中， 所述M个比特中与所述N个物理连接的标识对应的比特的值为1，其余比特的值为0，所述配置状态信息还包括请求比特和确认比特，所述请求比特用于请求接收端根据所述地图信息更新所述物理连接组的配置，所述确认比特用于接收端确认所述物理连接组的配置的更新。
物理连接组配置更新时，需要发送端与接收端进行协议交互和协商。现有技术通过传输多张地图(请求地图PHY MAP Request和激活地图PHY MAP Active)进行上述协议交互和协商，本身地图的信息量就很大，通过传输不同地图实现协议的交互会发送很多冗余信息，传输效率很低。本发明实施例通过设置请求比特和确认比特，将协议交互的过程通过额外的比特来实现，此时收发端仅需传一张表征物理连接组配置的地图即可，与现有技术相比，提高了传输效率。
可选地，作为一个实施例，所述每个物理连接的配置状态信息包含在所述每个物理连接上传输的子流的开销码块中。
可选地，作为一个实施例，所述每个物理连接的配置状态信息以基本帧为单位周期性传输。
可选地，作为一个实施例，所述每个物理连接的配置状态信息还包括物理连接组的标识。
下面以表7和表8为例进行举例说明。
表7开销区域210的一部分(31比特之前)
Figure PCTCN2016087312-appb-000007
表8开销区域210的一部分(32-39比特)
Figure PCTCN2016087312-appb-000008
结合表7和表8可以看出，在一个基本周期内的4个开销码块组成的开销区域中，共有4个字节(Byte)来传输物理连接的配置状态信息。如现有技术所述，物理连接的标识THIS PHY包括8个比特，因此，一个物理连接组最多包含256个物理连接。物理连接的标识、物理连接组的标识、以及物理连接组的地图信息，可以通过表9所示的方式传输。
表9物理连接的配置状态信息的传输
Figure PCTCN2016087312-appb-000009
表9示出了一个物理连接在10个基本帧周期传输的信息，从表9可以看出，本发明实施例通过10个基本帧周期就可以将配置状态信息传输完毕，与现有技术相比，提升了传输效率。
图18是本发明另一实施例的传输灵活以太网的数据流的方法的示意性流程图。图18的方法可以由接收端执行，该方法包括：
1810、通过物理连接组的N个物理连接接收N个子流，其中，每个物理连接上传输的子流包括所述每个物理连接的配置状态信息，所述配置状态信 息包括所述每个物理连接的标识，以及所述物理连接组内的地图信息，所述地图信息包括M个比特，M为所述物理连接组所能容纳的总物理连接数，其中，所述M个比特中与所述N个物理连接的标识对应的比特的值为1，其余比特的值为0，所述配置状态信息还包括请求比特和确认比特，所述请求比特用于请求接收端根据所述地图信息更新所述物理连接组的配置，所述确认比特用于接收端确认所述物理连接组的配置的更新；
1820、根据所述N个物理连接在所述物理连接组内的先后顺序，组装所述N个子流，恢复所述数据流。
本发明实施例通过设置请求比特和确认比特，将协议交互的过程通过额外的比特来实现，此时收发端仅需传一张表征物理连接组配置的地图即可，与现有技术相比，提高了传输效率。
可选地，作为一个实施例，图18的方法还可包括：当所述请求比特指示所述物理连接组的配置更新时，根据所述N个物理连接的配置状态信息，确定所述N个物理连接在所述物理连接组内的先后顺序。
应理解，与现有技术类似，本发明实施例中，物理连接的标识越大，该物理连接在物理连接组内的顺序越靠后。
